DYEING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 382,918, dated May 15,1888. Application filed December 12, 1887. Serial No. 257,624. (Nomodel.)

To all whom it may concern:

Be it known that I, URBAN WELDON, a resident of the city of Oohoes, inthe county of Albany and State of New York, have invented certain newand useful Improvements in Apparatus for Dyeing Yarn; and I do herebydeclare that the following is a full, clear, and ex act description ofthe invention, that will enable others skilled in the art to which itappcr tains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference markedthereon,which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to improvements in apparatus for dyeing yarn; andit consists of the novel construction and combination of partshereinafterdescribed, and pointed outin the claims.

This application is limited to an apparatus in which the yarn issupported by a detach able frame While the latter is carried through thedye-stuff by asuitable carriage, preferably r a rotary cylinder ordipping-wheel.

An apparatus in which the yarn is sup ported by the wheel without theintervention of detachable yarn-supporting frames while it passesthrough the dye-stuff will be made the subject of a future application.

Heretofore a rotary cage, wheel,or cylinder provided at or nearitsperiphery with pockets adapted to receive and carry fabrics has beenemployed to rotate, partly submerged, in a vat containing dye-stuff; butsuch pockets were not adapted to carry yarns. The yarn must be supportedin a position such that the dyestuff will permeate every thread, andsuch that the threads will not become tangled or knotted together.

One of the objects of this invention is to properly support the yarnwhile it is being carried upon the dipping-wheel, and another is tofacilitate the operation of securing the yarn in a proper position onthe wheel.

Figure l of the drawings is a side elevation of my improved apparatus.Fig. 2 is an end view of same. Fig. 3 is a vertical crosssection takenon the broken line was in Fig. 1. Fig. 4 is a plan view of ayarn-supporting frame with the cover removed, and showing skeins of yarnsupported in different positions thereon. Fig. 5 is a front elevation ofthe frame,sl1owing the cover closed and yarn upon ,wo pins. Fig. 6 is avertical cross-section of same,taken at broken line a: 00 in Fig. 5.Figs. 7, 8, and 9 represent modified forms of yarnsupporting frames, thelast figure illustrating a means for adjusting the length or width ofthe frame.

The vat A, which contains the dyestuff, may be of an y desiredshape,though preferably with asemicircular bottom, B,adapted to fitapproximately the periphery of the dipping-Wheel or cylinder 0. Theheads D of the tank are held together by bolts or rods a, the heads a ofwhich have a bearing upon the plate I). The wheel is mounted upon ashaft, E, which has its bearings in the heads of the vat, and may beprovided with a driving-pulley, F, fixed thereon.

The dipping-wheel is preferably composed of two circular heads, G,supported by the shaft E,which passes centrally through them, and theradial partitions H, which extend from head to head and form theintervening pockets J, adapted to receive the yarn-supporting frames K.

The partitions H may be perforated, as seen at d,or they may be openorlattice work,similar to that in frames K.

The frames may be of any desired form, to be inserted, severally, in therespective pockets of the wheel. I prefer to make them rectangular inshape and of a width or length a little less than the distance betweentheheads of the wheel, and of a length or depth to be wholly receivedwithin the wheel-pocket. The

frames are preferably made of lattice-work having the cross-slats e,forming a base from which pins or sticks P may be erected to support theyarn. The yarn is customarily and preferably handled mounted upon sticksor pins. The yarn is stuck upon the pins erected from the frames inskeins stuck or by slipping one end of a skein, S, over one pin and theother end of the skein over another pin at a suitable distance from thefirst, to keep the individual threads of the skein approximatelyparallel to each other, and yet loose enough, so that as the skein hangsvertically, after being weighted by the dye-stuff, the lower end willfall away from the lower pin and permit the dye-stuff to permeate allthe threadsalikewhich it would not do ifany portion of the skein werekept in contact with a pin continuously throughout the operation ofdyeing the yarn. The elongated position of the skein is shown by dottedlines forming an extension of theleft-hand skein in Fig. 4.

The yarn may be hung in many different positions, according to thelength of the skein, as shown in Fig. 4. The frames may also be providedwith a cover, f, hinged at one side to the frame, the other side beingadapted to swing to and from the tops of the pins to facilitatetheinsertion of theframesinto the pockets in the wheel.

The cover may be perforated with holes or made of lattice-work, like thebottoms of the frames.

The skeins of yarn may be doubled upon themselves and stuck upon onepin, as shown in Fig. 7.

Instead of the pins,a light frame-work similar in form to pigeon-holesmay be erected from the bottom of the frame, as shown in Fig. 8, eachone of the small compartments 9 being adapted to receive andcontain askein of yarn.

The same frames can be used with either long or short skeins of yarnwhen made in sections adjustable relatively to one another, as shown inFig. 9.

The section at is secured to the section 71. by means of the screwq,passing through ascrewthreaded nut secured to the section m, andloosely entering an aperture in the block 1, secured to the section 11.

The screw is provided with a wrench or handle, (1 by which it may beturned to force the sections apart, the natural tension of the yarntending to draw them together.

Any well-known adjusting device may be employed to control the relativeposition of the two sections.

The section m is represented as having been forced out by the screw fromthe position shown by the dotted to that shown by the solid lines.

In the use of the word perforated I do not wish to be limited to anyparticular kind or class of openings or to exclude lattice-work.

WhatI claim as new, and desire to secure by Letters Patent, is

1. In an apparatus for dyeing yarn, in combination with arotarydipping-wheel provided with partitions forming compartments, a series ofremovable frames adapted for insertion in said compartments and providedwith pins for holding yarn, substantially as and for the purposesdescribed.

2. In an apparatus for dyeing yarn, in combination with a rotarydipping-wheel provided with pockets formed by radial open-workpartitions, a series of removable frames provided with fixed pins, andhinged lids adapted to fit in said pockets, substantially as and for thepurposes described. 65

3. Incombination with a dipping-wheel divided into compartments,substantially as shown, a series of removable frames provided withyarn-holding devices and adapted for insertion in said compartments,each of which frames is constructed in two sections which are adjustableto or from each other,whereby the frame may be extended or reduced,substantially as set forth and described.

4. In combination with a dipping-wheel provided with radial partitions,a series of frames, K,each having an open-work base provided with fixedpins P, and a hinged lid, f, substantially as and for the purposesdescribed.

In testimony whereof I have hereunto set my hand this th day ofDecember, 1887.

URBAN WELDON.
